Installation of 42 deepwells, unwatering system, rewatering system, and operation and maintenance for project crossing Navigation Canal. Alberici conceptualized several accepted innovations during pre-construction that reduced risks and project costs during construction, including a temporary rock dike across the canal that reduced tidal flow to allow for use of a cofferdam and design/build dewatering system. The contractor backflled the scour hole with SP Sandy Soils and Griffin jetted deep wells that extended up to 75 ft. deep in the canal section of the project. This allowed for a subgrade of EL -28 to be achieved.
